Thank you, i'll try shorting a triac in the morning, insulated long nose pliers will do!

having looked through a couple of data sheets i think that the problem is frequency. i tried a different inverter which gave 6khz and the voltage at the outputs was down to 30v.
w04 0103mn is the triac. the closest datasheet i found was for a z0103mn, didn't mention the frequency range but seems to assume mains frequecies. on the sparkfun website they talk about 425hz, perhapse the board is designed for that, i've got 3 inverters, the lowest being 3khz.

anyone got a schematic for a 125v 425hz inverter that runs from 5 - 12vdc?

it's odd that the "status" light doesn't come on.

i'll try some shorting.
